无人机倾斜摄影测量在矿山生态修复测绘中的应用

Application of UAV Tilt Photogrammetry in Mine Ecological Restoration Surveying and Mapping

本文旨在介绍利用无人机倾斜摄影测量技术对矿山进行数据采集,发挥无人机倾斜摄影测量灵活高效、高分辨率、低成本的优势,三维实景展现测量区域的地形地貌。利用大疆无人机进行倾斜摄影测量,使用大疆智图软件对采集数据进行自动化处理,建立矿山高精度实景三维模型,通过三维模型地物特征点的坐标高程与外业采集检核点进行对比及三维模型实景展现,分析无人机摄影测量在矿山生态修复测绘中的应用优势。

This article aims to introduce the use of UAV tilt photogrammetry technology to collect data in mines, to take advantage of the flexibility, efficiency, high resolution, and low cost of UAV tilt photogrammetry, and to display the topography of the survey area in a three-dimensional real scene. This paper uses DJI UAV to perform tilt photogrammetry,uses DJI Terra software to automatically process the collected data, establishes a high-precision real-scene three-dimensional model of the mine, and passes the coordinate elevation of the feature points of the three-dimensional model and field collection check points. Compare and show the real scene of the three-dimensional model, analyze the application advantages of UAV photogrammetry in mine ecological restoration surveying and mapping.
